Server exits immediately when starting server with --socket argument

[cotigao]

I checked out the code and ran all the necessary build and installs on a linux (ubuntu 19.04) machine. Ran the following command to launch the server.

docker-langserver --socket=3000

The moment I run the above command, the server just exits on its own.

> tsc --version
Version 3.9.5
> node --version
v12.16.3

@cotigao Did you open up port 3000 so that it is listening for connections?

[cotigao]

@rcjsuen oops! Guess I got the understanding wrong. I thought the LSP server would be listening on 3000 and the client (IDE) would connect to it. So turns out the client (IDE) needs to start a server that's listening, which means the LSP server (that acts like a client )connects to the client (IDE, which is a server listening on port 300). Please correct me if I have got it wrong, if you feel

@cotigao That is correct.

@rcjsuen If I may ask, is there a specific reason to have it that way?

[rcjsuen]

@cotigao See https://github.com/microsoft/vscode-languageserver-node/issues/245#issuecomment-336054699.

@rcjsuen Thanks! That seems a bit counter-intuitive. But then I guess it is fine because LSP does not mandate on what medium is to be used for the server and client to establish the connection and to exchange messages.

We can close this issue. Thanks for the prompt respone.
